Description
Pouring rings in polypropylene (PP) are practical accessories for laboratory bottles and containers with a thread 45 closure system. The green rings support controlled pouring and help limit drips when transferring liquids during routine bench work. Supplied as a pack of 10 pieces, they suit everyday handling of reagents, buffers and process media where a reliable pour lip improves workflow. Made from durable PP, the rings offer the chemical resistance typical of this polymer together with a lightweight form that is simple to fit and remove. Green colour coding makes them easy to spot among other bottle accessories. The pack weighs only 0,006 kg, so storage and logistics stay straightforward. These pouring rings from manufacturer DWK Life Sciences integrate into standard labware setups for containers, bottles, seals and related accessories. They are intended for compatible thread 45 vessels in research, quality control and general laboratory environments where directed pouring supports cleaner handling and reduces spillage.

Questions about Pouring rings, PP, green, thread 45, 10 unit(s)
What is this article?
Pouring rings, PP, green, thread 45, 10 unit(s) is the article on this page. Luminix Health distributes DWK Life Sciences for laboratory use. It sits in Screw caps & closures, inside Stoppers, caps & closures, in Labware.
A screw cap has a thread and a liner. The thread has to match the bottle. The liner has to survive the liquid: a pulp liner fails in a solvent that a PTFE-faced liner ignores. The colour of the cap is not the specification.
A closure is the part that decides whether a bottle stays shut and whether the contents attack the seal. A ground-glass stopper matches a ground neck. A screw cap needs the right thread and a liner that survives the liquid. Rubber and silicone stoppers push into a mouth. The liner, not the colour of the cap, is the chemical choice. The vessels they close are indexed under ISO laboratory glassware.
